                                        <p>Donald Davies has contributed in many fields including Pilot ACE, London's first general purpose stored program electronic digital computer.</p>
                                        <p>Davies was  influenced by a lecture from John Womersley, superintendent of the mathematics division of the National Physical Laboratory (NPL), about the ACE digital computer which was being developed there. So he immediately applied and joined the ACE group in the Mathematics Division  on 1<sup>st</sup> September 1947.</p>          
                                        <p>He  played a key part in the detailed design and development of Pilot ACE (based on original designs of Turing for ACE, Automatic Computing Engine)  with Ted Newman, Jim Wilkinson and others. Here is a brief history of the development of Pilot ACE computer in London.</p>
